The most basic requirements for joining the United States Marine Corps are being between the ages of 17 and 29 at the time of enlistment, being a documented legal resident of the country and having a high school diploma. Recruits also have to pass a physical examination.
The physical examines both medical health and basic physical fitness. Most life-threatening or contagious diseases or conditions disqualify an applicant from enlisting.
Single applicants must also have no dependents, and married applicants can have no more than two dependents. A spouse does not count as a dependent if they have their own income.
Special waivers are available for some requirements.
